If the points \((2, -3)\), \((\lambda, -1)\) and \((0, 4)\) are collinear, then the value of \(\lambda\) is

[Figure: Mapping diagram of a relation f from set A = {a, b, c} to set B = {1, 2, 3, 4}. Arrows: a to 1, a to 3, b to 2, c to 4. So element a has two arrows (to 1 and to 3).] Which of the following is true on the basis of above diagram?

The value of \(\sin\left[2\cot^{-1}\left(\frac{-5}{12}\right)\right]\) is:

Let \(y = m\sin rx + n\cos rx\). What is the value of \(\frac{d^2y}{dx^2}\)?

\(\int_{1/3}^{1}\frac{(x - x^3)^{1/3}}{x^4}\,dx =\)

The integrating factor of the differential equation \(\cos x\frac{dy}{dx} + y\sin x = 1\) is

If \(0 < x < \pi\) and the matrix \(\begin{bmatrix}4\sin x & -1\\ -3 & \sin x\end{bmatrix}\) is singular, then the values of \(x\) are:

The order and degree of the differential equation \(\left[\left(\frac{d^2y}{dx^2}\right) - 3\right]^{\frac{1}{3}} = 2\left(\frac{dy}{dx}\right)^{\frac{1}{4}}\) are
